Question

How many moles of CO2 would be produced when methane fully reacts with 6 moles of O2?

a) 6 moles of CO2
b) 12 moles of CO2
c) 3 moles of CO2
d) 24 moles of CO2

Answer 1

The correct answer is c) 3 moles of CO2. By using the balanced chemical equation for the combustion of methane, we find that 3 moles of methane would react with 6 moles of oxygen to produce 3 moles of CO2.

Step-by-step explanation:

To calculate how many moles of CO2 would be produced when methane fully reacts with 6 moles of O2, we first need the balanced chemical reaction for the combustion of methane (CH4):

CH4 + 2 O2 → CO2 + 2 H2O

From the balanced equation, each mole of methane reacts with 2 moles of oxygen to produce 1 mole of carbon dioxide. Since 6 moles of oxygen are provided, this would be enough to fully react with 3 moles of methane, thus producing 3 moles of CO2.
